(Savez hemijskih inženjera, Beograd, 2018)
Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than ...
Influence of track stiffness on track behaviour under vertical load
(University of Zagreb, Faculty of Transport and Traffic Sciences, 2012)
The analysis of track behaviour under vertical load is traditionally based on the presumption that the stresses and deformations in track elements can be determined by the application of the Winkler's Hypothesis. The rail ...
Fly ash and slag utilization for the Serbian railway substructure
(Vilnius Gediminas Technical University, 2016)
Approximately 7 million tons of fly ash and slag are produced in thermal power plants in Serbia every year, only 3% of which is used in the cement industry. About 300 million tons of the ash-slag mixture are disposed in ...
